3.3.1 Sample Definition Step When you want measurement using Stress or Strain, the Sample Definition step MUST be used. NOTE You must use the Sample Definition step in order to measure stress or strain. The Sample Definition step is used to specify the sample under test, specifically its shape and area. Stress and strain require the sample area. When the Sample Definition step is used, the graphing options are: • Stress x Strain ( σ x ϵ ) • Stress x Time ( σ x T) • Strain x Time ( ϵ x T) NOTE If the Sample Definition step is not used, the graphing options are restricted to: • Load x Distance (L x D) • Load x Time (L x T) • Distance x Time (D x T)
